7 Be i known that I, GnononA. MollIrLLnfi. acitizen of the United States, and a resij dent ofAlton', in the county of St. Clair,

State oflllinois, have invented new and useful Improvements in 'Hernial Trusses, of.

which the following is a specification.

This invention relates to hernial trusses adapted for the treatment and relief of 10 ruptures. Ruptures occur in various positions in the abdominal walls, and accordingly," the required truss must notonly the body of the patient, but the pad must be adjusted to correspond to the position of the rupture. In any adjusted position,

the pad must apply a yielding upward pressure on the rupture in order to properly s1 form its supporting function and this action must be obtained whether. theirupture is a right or a left one. y p y ,One of the. objects of this invention, therefore, is to provide a truss which. isof unii versal application and which can be not only adjusted for right and left ruptures; but also in accordance with the size of the patient and the position of the rupture.

A further object of this invention is to provideimproved means for attaching the pad as well as theback disk to the'bowed truss-wire or spring, in such a manner that the pad will more perfectly fitthe rupt r and supportv the same automatically during the various movements of the body, whereby the'truss will be more comfortable further object of this invention is to providea surgical truss in which novel means for supporting and adjusting thepad are made use of, together with a novel ar- 40 rangement of a torsional retaining-spring adapted to betensioned as delicately as'desired, and which isdesigned to act upon the pad-support, after the latter has been ad- 1, justed, to automatically maintain the pad yijeldinglyyet comfortably in contact with the rupture.v I j further object of this invention is to provide an improved and automatically a djustable back-disk which is connected with.

.50 the supporting wire or. spring by novel and efiicient .means which will allow of its adjustlnent to fit lean and stout persons with the same. supporting wire, and to automatically maintain its pivotal. connection with right ruptures and [Figure 2 is an enlarged detail side el e-I vation of the pad and its connections;

Referring to the accompanying drawing and more particularly to Figures 1, 2, 4, an 6 to 9 inclusive, 1 designates a supporting band which is, in this case, in the form of a bowed wire or spring,' provided witha hook Q-at one of its ends and with a'hook'3 at its oppositefend detachabl secured in place by having its internally t readed bo'dy enga'g ing he threaded end of'sha'nk3 of the pad in position to treat.

porting band. The usual sheath Q of rubber or other suitable material is provided for said supporting band for an obvious purose. I. P A collar 5 is fixed upon the shank35 by means of a set screw 6 at a pointadjacent the book 3, and this collar carries a stop pin 7'which projects from the inner face-of the collar in a direction parallel with the shank 35 and engages a slot or recess 8 in a carrier,

which is rotatively mounted on the shank and has its endformed to-provide a ball 9. The-pin and slotYt-herefore permit limited rotative movement of the carrier on [the shank. f i l 1 i v. The outer surface of the ball 9 ,is spherical form and is: engaged by a socket IQ r formed in a baseplate 11 secured to a pad 12, which pad may be of the usual form and faced with leather. Cooperating with the socket 10 is a U-shaped loop 13 having a socket 14 of spherical form' located diametrically opposite the socket 10. One end of the loop or stirrup is flexibly connectedto the base plate and is readily detachable therefrom by having a bent portion 36 loosely engaging in a slot 15 formed in a base plate; the other end of the loop is flexibly connected to the base plate by means of an adjusting and clamping screw 16 passing loosely through a perforation formed in an ear 37 on the loop and having a threaded connection with the base plate. With this construction, the screw 16 is adapted to draw the loop against the base plate so as to firmly clamp the ball in the sockets formed by the base plate and loop. With this construction, therefore, the pad can be adjusted on the carrier transversely and along the axis of the band and shank,

and can be clamped and firmly secured in any desired adjusted position. The base plate is secured to the pad by means of screws 17 V a The carrier is provided with a. tubular shank 18 which extends inwardly along the shank. A shifting element 19, in the form of a sleeve closed at one end, is mounted to slide and rotate relative to the carrier on the shank. A coiled spring 20 encircles the shank 35 and is housed within the tubular shank 18 and the sleeve 19 and bears at one end against the carrier and at its other end against the shifting element. The ends of this spring are bent axially as shown 'at 21 and are fixed within holes or recesses in the ends of the carrier and the shifting element. The spring, is, therefore, connected at one end to thecarrier and at its other end to the shifting element forming an abutment for the spring.

The shifting element is provided with one or more axially projecting pins 22 adapted to engage with a series of axial recesses 23 arranged circumferentially of a collar 24 fixed to the shank 35 and forming a stop for the shifting element.

Assumingthat the spring is under tension, this spring will act on the carrier to rotate it until one end of the slot 8 therein engages with the pin? on the collar 5 fixed to the shank 35 This will place the pad in the position where it exerts an upward yielding pressure on the rupture, the pad being movable in the direction of the arrow against the yielding tension of the spring through limited distances determined bythe length of the slot 8, but its movement in either direction, and especially in the upward, direction, being limited by the" engagement of the end of the slot with the pin 7 as shown in Figure 6. The result shifting element fan is, therefore, that the pad will always exert a yielding upward pressure'on the. m1 ture as is ,desirable and necessary. It Wi l, of

course, be understood that the supporting or decrease the spring tension as desired.

In order to permit such adjustment, the shifting element which is knurled, as shown in Figures 1 and 2, is moved to the right Figures 2 and 4, until the pins 22 arefree of the recesses 23; the shifting element is then rotated in the desired direction until the proper adjustment is obtained and the pins are then allowed to snap into the nearest set of recesses 23. The adjustment being completed, the parts are firmly retained in adjusted positions.

In order to adapt the truss for either right or left ruptures, the inclination of the pad must be reversible so as to always exert a yielding upward pressure. Thus, it will'be seen that where as in-Figures =1 and 9, the truss is adapted for a right rupture, if the pad is placed on the left side by turning the truss over, the inclination of the pad must be reversed as shown in Figure 10. This can be'accomplished by the construction embodying this invention. It will be noted that the ends 21 of the spring are fixed respectivel in "the 'carrier and that the spring is adapted to apply a yielding-tension whether coiled or uncoiled. Accordingly, to adjust the device to a left rupture, the shifting element is moved to the right, Figure '2, until the pins 22 are free 'of the recesses 23, and the element is then rotated on its supporting shank until the tension of the spring is entirely relieved; the rotation of the shifting element is then continued through "a suitable angle so as to apply a yielding tension to the spring in the opposite direction, thereby causing the carrier to shift rotatively until the other end of the slot '8 engages the pin 7 as shown in dotted lines 6, thereby shifting the pad'to the position shown in Figure 10. In this shiftedposition of the pad, a yielding upward pressurewill be applied to a left'rupture.

It will, therefore, be seen that in accordance with this invention, the pad is positioned on the supporting band so as to adapt it for right and left ruptures, and means are provided for selectively positioning the pad for such right and left rupturesandto apply a yielding upward .prewure to the rupture in either of these positions. This can *be accomplished without "disassembling the truss and without "disturbing-any of the permanent connection-s; accordingly, the ad- 'justments can.='b e"made by an =ord1nary drug v gist and without anytools." Moreoverythe mounting of the pad on thecarrier permits universal adjustment oflthe pad so as to back dis the body. j A'back-disk25 ma'de of hard rubber or the adapt the'truss to'the variousconditi'ons encountered in the particular case under con Isid'eration.
